Using heat and mechanical loads, forming metal uses deformation to modify metal objects. Unlike other metalworking services, this technique doesn’t involve adding or removing any material, so its mass stays the same.
Increasing the temperature of the metal material reduces its yield strength and increases ductility, thus making it easier to deform. Other techniques of forming metal include:
- Indenting – a tool is pressed into the metal workpiece.
- Rolling – the metal workpiece passes through two rotating rollers.
- Die forming – the metal workpiece is stamped by a press around or onto a die.
The process of merging two or more pieces of metal together is called joining metal. Various techniques can be used to join metal, including:
- Welding – welding is one of the most common approaches to joining metal. Using a combination of intense heat and pressure, the materials are fused together and a filler material is added to form the welded joint.
- Brazing – brazing is a thermal joining process whereby a metal filler is heated and melted to bond and join the pieces of metal.
- Soldering – soldering is very similar to brazing, only it involves lower temperatures and is softer. It is usually the chosen method for instances when a good electrical connection is needed.
Many different types of tools and technologies are utilised when it comes to metalworking. Because metalworking is used in a variety of sectors and to create an array of products and structures, a wide range of manufacturing tools are used.
Whether it’s basic tools like hammers, drills and hacksaws or complex and intricate machines like CNC mills, laser cutters and lathes, all are crucial to producing excellent metal products.
